Key Points:
- Oura marketed 95% sleep staging accuracy vs. clinical labs; complaint alleges the ring can’t detect the physiological signals real sleep labs use.
- The “sleep score” is alleged AI guesswork off peripheral signals (heart rate, movement, skin temp), no more reliable than a coin flip per the complaint.
- Filed in N.D. Cal., San Francisco, seeking injunctive relief and restitution for purchasers.
SAN FRANCISCO, CA – Clarkson Law Firm, the prominent national public interest firm, filed a class action lawsuit against Oura in the US District Court for the Northern District of California, San Francisco Division, on behalf of all Oura Smart Rings purchasers. The false advertising suit alleges that Oura deceives consumers about the accuracy of its sleep tracking features. The product cannot measure any of the physiological signals required to determine sleep quality or sleep stages. Instead, it delivers only AI-generated guesses that, according to the Complaint, are no more reliable than a coin flip.
The wearable tech industry has caused consumers to grow increasingly infatuated with their health data – counting every step, logging every workout –– and sleep tracking is among them, emerging as a major health priority for millions of Americans. Products such as the Oura Ring have reduced rest and recovery into numbers on a screen. Oura built its market-leading position on the promise of accurate sleep tracking, but what users receive each day are faulty AI inferences based on peripheral signals, not actual sleep measurement.
“Oura claims to provide consumers with a holistic sleep health analysis, but the ring doesn’t actually produce an accurate score of an individual’s sleep quality,” said Shireen Clarkson, co-founder and partner at Clarkson Law Firm.
“Yet people are making real health decisions based on that feedback – from adjusting nightly routines and dietary choices to seeking, or delaying, medical attention. The reality is, consumers are paying a premium price, up to hundreds of dollars a year, and handing over their most personal health data to a big tech company. But what they get in return is a mere guess dressed up as science.”
Oura customers are being sold smart devices that promise to help them better understand their bodies through sleep data, and thus a growing share of people wake up and check their Oura “sleep score” before they even check in with themselves. Simply put, Oura is selling consumers on the idea of accurate sleep that is anything but.
“When people rely on a device to guide decisions about their health, misinformation cannot be tolerated,” said Ryan Clarkson, co-founder and managing partner at Clarkson Law Firm. “Oura users trust that the numbers on their screen reflect reality. People structure their days, interpret the way they feel, and design their lives around inaccurate figures spit out by these devices. Marketing an inaccurate sleep tracker as precise and reliable is dangerous because people believe it – and change their behavior accordingly.”
As the complaint details, the Oura Ring cannot accurately measure the metrics needed to determine sleep quality and instead uses guesswork and faulty AI inferences to guess what is happening within someone’s body, taking advantage of consumers who struggle with sleep health or care deeply about it.
“Oura built an 11-billion-dollar company on the promise that its ring can accurately measure sleep and its stages. But sleep doesn’t happen in one’s finger. It is defined by brain activity, eye movement, and muscle tone,” said Yana Hart, partner at Clarkson Law Firm. “Oura’s product doesn’t measure any of that. The numbers it provides are nothing more than guesswork based on markers it can measure, such as heart rate, movement, and skin temperature.”
Clarkson’s complaint filed today calls on Oura to stop deceiving its consumers and falsely advertising its product with characteristics and qualities it does not deliver. Through the lawsuit, Plaintiffs are seeking injunctive relief to force the Defendants to stop misrepresenting their product as well as restitution for buying these products based on the Defendants’ false claims.
